Abstract: The disclosure relates to a work machine, in particular a duty-cycle crawler crane, having an undercarriage which comprises a middle part and at least one crawler carrier connected to the middle part and having at least one electric traction drive, wherein at least one energy transmission line for supplying power to the traction drive and at least one further supply line runs between the traction drive and the middle part. According to the disclosure, the at least one energy supply line and the at least one further supply line run together in a separate protection means outside the middle part and the crawler carrier.

Abstract: The disclosure relates to a work machine, in particular a duty-cycle crawler crane, having an undercarriage which comprises a middle part and at least one crawler carrier which is connected to the middle part and comprises at least one electric traction drive, wherein at least one supply line runs from the middle part to the traction drive and is connected to the latter in a disconnectable manner via a first connection. According to the disclosure, the work machine comprises an electrical interlock loop, which is connected to the traction drive via the first connection, and a mating plug connector module, which is arranged on the undercarriage and has a first mating connection for connecting to the first connection of the supply line and is configured to bridge the interlock loop, which is interrupted by a disconnection from the traction drive, in a current-conducting manner.

Abstract: Disclosed are a method for the anaerobic treatment of pulp-containing waste and a fermentation plant for such products, wherein they are first of all mechanically prepared and comminuted, subsequently diluted to a predetermined dry matter content by the addition of process water or the like, and sanitized and anaerobically fermented in a subsequent method step. The remaining rotted residue is divided into a plastics-rich and a pulp-rich fraction, and these fractions are conditioned in conditioning stages to recyclable materials, or to fuel, or to products adapted to be deposited.
